Abstract
A paramagnetic cobalt-SiH intermediate possessing the Co-(eta(1)-H-Si) moiety was studied using various spectroscopic techniques. Frozen solution ENDOR experiments show a Co-H distance of similar to 1.53 angstrom and a Si-Co-H angle of similar to 15 degrees, whereas XRD data suggest a TBP geometry about a Co(II) centre. Its stepwise deprotonation with base followed by dehalogenation was identified experimentally and theoretically.
